OLDMAPSONLINE.ORG:
OPEN SOURCE AND ONLINE TOOLS FOR OLD MAPS
Moravian Library Brno: OldMapsOnline.org
R&D grant of the Czech Ministry of Culture (DC08P02OUK006)
FOSS4G 2010 - OSGEO, Barcelona, 6-8 September 2010

3. PROJECT OLDMAPSONLINE.ORG
• Research project of Moravian Library in Brno, Czech
Republic (Bernhard Moll’s Map Collection, 12k+ scans).
• Development of a workflow based on open-source
software: to assist in the management, manipulation and
visualization of historical map collections on the web
• Best practices and step-by-step guides for use of the
free software
• Online tools to explore, georeference, annotate and
visually integrate online old maps in a Web 2.0 style,
following OGC standards and known best practices

4. THE RESULTS?
1.Documentation and links to free software tools, and
relevant scientific articles. Presentations.
2.We have produced open-source software you can use
right now for publishing your scanned maps online:
IIPImage JPEG2000, MapTiler, .. + contributed patches
in OpenLayers (Zoomify), GDAL (gdal2tiles), GeoTools
3.An online service: Georeferencer.org

8. JPEG PUBLISHING OF THE SCANS
2000
• Easiest and fastest: Zoomify or DeepZoom/OpenZoom
via “prerendered tiles”. Step by step tutorial:
http://help.oldmapsonline.org/publish/
• Image Server software as an alternative:
• For collections with thousands of images and their
own hardware servers connected to the Internet
• Possibly one image file for both online distribution
and digital archiving (“open archive”)
• Save the disk space thanks advanced compression

9. OPENLAYERS, ZOOMIFY, MOOVIEWER, OPENZOOM
TILES PREGENERATED OR SERVED BY IIPIMAGE

10. JPEG IIPIMAGE JPEG2000
2000
• Free and open-source software, runs best on a Linux server
• Compatible with several popular viewers (Zoomify, SeaDragon,
IIPMooViewer, OpenLayers, PanoJS, ...) and iPhone or Google
Earth
• Easy to install (prepared step-by-step tutorial and a Debian
package)
• Alternative to commercial products such as Lizardtech
ExpressServer (MrSID), ERDAS Image Web Server (ECW)
• Direct distribution of TIFF images (with encoded pyramid)
• Support for JPEG2000 format (via Kakadu library - non-
commercial use only, 100% free OpenJPEG library later on)

11. 400 DPI
9606 x 7322 px
202 MB uncompressed TIFF
~107 MB JPEG2000 (lossless)
15 MB JPEG 85%
~ 8 MB JPEG2000 (lossy)

12. JPEG IIPIMAGE JPEG2000
2000
• Considering to use JPEG2000 format for archiving?
• Do you want to publish high resolution images online?
• Have a look at our open-source project!
• Documentation, best practice articles related to
encoding to JPEG2000, software for download:
http://oldmapsonline.org/jpeg2000/

32. PUBLISHING OF THE MAPS
• Easiest and fastest: prerendered tiles via MapTiler:
http://www.maptiler.org/
• Alternative to map servers, which are harder to install/
configure/maintain:
• MapServer, GeoServer, ...
• Available on the OSGeo LiveDVD!
• It generates OSGeo TMS tiles, same like GDAL2Tiles.

ONLINE SERVICE
GEOREFERENCER.ORG

35. WHAT IS IT?
• Online tool designed to bookmark, georeference and
annotate high resolution images of maps on the web.
• Collaborative Web 2.0 online service for all of us!
• You can create your personal virtual map collection and do a
research and genealogy studies online.
• Share the results of your work with online old maps, compare
and synthesize maps published at different websites
• Automatic 3D visualization and overlays of Google Maps-like
base maps
• You need only a web browser to process the maps!

36. DEMO
http://georeferencer.org/
Still under development!
PUBLIC ALPHA VERSION
AVAILABLE NOW!

38. PLANS FOR THE FUTURE:
• Customization for libraries, adding of metadata.
• Clipping, composites of maps, correct merging of map series
• Map projections and custom coordinates (EPSG)
• Reference maps via OGC WMS - from national authorities
• Closer integration with library websites (via a link)
• Improvement of the community services, comments, links to
research, etc.
• Image analysis: “colored version of ...”, automatic neat line
detection, cropped maps and derivatives, deduplication
• A free service, hopefully a new grant (MZK + CUNI + MU)

39. WE NEED YOUR HELP!
• Try it and submit “feedback” via the online button!
• Ideas for improvement? Do you want to collaborate?
• Developers? We have a REST API to access the data.
Need for JavaScript API for development of external
tools?
Please contact us, feedback wanted!
http://georeferencer.org/
Support for all JPEG images, Zoomify maps and David Rumsey’s maps with and an improved
georeferencing interdace now! Support for more formats of maps coming soon!

40. ONE MORE THING...

41. GEOGRAPHICAL SEARCH
• Intuitive interface: Where, When, Who, What
• Ranking to sort the maps, even in a large catalog
• Tested projects:
• TimeMap.net - (ECAI.org)
• Alexandria Digital Library
• DigMap.eu Lucene GeoTemporal (LGTE)
• Google GeoSearch API
